When do you overload an operator in C #?

Which is an example of an overloaded operator?
The following example defines a simplified structure to represent a rational number. The structure overloads some of the arithmetic operators: You could extend the preceding example by defining an implicit conversion from int to Fraction. Then, overloaded operators would support arguments of those two types.
